File:NASA Black Hole Visualization Takes Viewers Beyond the Brink (SVS14576 - Plunge Times Still 03900).jpg

English: Plunge clock comparison. This movie tracks the local time of the falling camera, the time as experienced by a faraway observer (coordinate time), and the maximum blueshift observed. This is the factor by which the frequency of light in the direction of travel is increased. At 42 seconds, coordinate time reads all 9s, indicating that the camera has crossed the event horizon and external time is infinite. The blueshift continues to climb, exceeding 43 by the end, which indicates motion exceeding 99.9% light speed.Credit: NASA's Goddard Space Flight Center/J. SchnittmanVisual description: A box on a white background contains three lines of text. The top line reads "local time," the second line reads "coord time," and the third reads "max blueshift." As the video plays, these times increase and diverge as described above.
